1 May 2006: The International Standards Organisation has today approved a standard file format to be used worldwide for the storage of files produced by office software (word processor documents, spreadsheets, presentations, drawings, etc.). For the first time in the history of computing, software users will be guaranteed that they will be able to use their data in any compliant software package, both now and in the future. The point of an open standard is that any compliant application can use it.http://www.openoffice.org/press/iso_pr.html
